Lots of dance companies create new works, but most pieces go as quickly as they come. A troupe will present its “world premiere” with a splash, then the routine disappears into the repertoire, never to be danced again.

It helps, of course, that “Carry On” is a collaboration with the local band Paper Bird, whose folksy, voices-upfront sound has won it a growing number of fans across the country. The piece pulls audiences from both the concert and dance crowds.

“Carry On” is also the kind of work that can stretch comfortably to a larger house. With bright lights and busy projections, the piece lasts a full evening and features 10 dancers and seven musicians.

BNC’s Garrett Ammon, who choreographed the work, said there will be a bit of tweaking on the movement this time around and one new song, but basically the original is a natural fit for the Ellie.

The whole collaboration between BNC and Paper Bird was based on “a shared feeling about the way we enter into the world,” Ammon said, where traditional artistic styles are delivered with a contemporary sensibility.

BNC presents classical ballet heavily influenced by modern dance. Paper Bird’s music has a deep reverence for pop’s rootsy past, but it manages to be an alternative to the usual radio fare. Some have described their style as “folk-Baroque.”

“Their sound is at once new and old. It feels like it’s always existed,” said Ammon, giving a nod to his artistic partners. “We try to do the same thing in the dance we create.”

He extends those timeless attributes to the Ellie Caulkins Opera House itself. The historic structure was built in 1908 and has an elaborate shell with neo-classical touches. But inside it’s new, thanks to a $92 million renovation in 2005, that placed a freestanding, performance bowl in the center.

“Dance really needs to be experienced in a more intimate space,” said Ammon. “But if there’s one piece that can take on that size theater, it is this one. It’s not going to get lost.”

Ammon has the same hope for “Carry On” as a work of art. The performance coincides with a sizable meeting of arts presenters taking place in Denver through the weekend. The Western Arts Alliance’s annual conference brings about 750 people to town.

A large Denver audience will see the Ellie event, but so will the major players who book theaters and college campuses from Kansas City to Seattle. Ammon would love to have his decade-old company land a few gigs out of it.

“We haven’t been seen outside of our home state yet, and we’re anxious to be able to share what we’ve been doing with a broader audience.”

In Washington, there may be no more loathed profession than that of the lobbyist. The political thriller “Miss Sloane” paints a cynical behind-the-scenes picture of the great lengths to which paid advocates will go to advance a cause.

The Denver Art Museum plans to funnel a $25 million one-time gift into the estimated $150 million budget for renovating its iconic North Building in time for the structure’s 50th anniversary in 2021, officials announced Thursday.
